ARTHUR O. TAYLOR, OF BROOKLYN, 'NEW YORK.

STEREOTYPE-BLQCK.

.To all whom itmay concern:

Be it known that I, ARTHUR O. TAYLOR,

a citizen ofthe United States, residing at.

Brooklyn, in the county of-Kings and State of New York, haveinvented-new and usefulImprovements in Stereotype-Blocks, of

which the following is a specification.

This invent-ion relates to stereotype blocks and more particularly tothelocking means for securing the plate to the block totemporarilyretain same while prints are being made from the plate and toquickly release same so that a new plate maybe substituted.

The invention not only embraces the locking means itself but also meansby which the :locks'may be immediately adjusted to accommodate plates ofvarious sizes, all of which will be more fully described in thefollowing specification, set forth in the claims and illustrated in thedrawings accompanying this application, wherein:

Figure 1 is a plan view of a stereotype block with the improved locksapplied thereto. Fig. 2 is a longitudinal sectional view through one ofthe locks. Fig. 3 is a front view of a lock recess. Fig. 4: is a crosssection through a lock in its operative position. Fig. 5 is a similarview with the jaw of the lock disengaged. Fig. 6 is a perspective Viewof the aw and its collar.

The invention consists primarily of a look, any number of which may beapplied to a block of the desired size, the larger the block there isconsequently necessary more locks, and these locks are arranged aroundthe sides of the block in the most advantageous manner but preferably insets opposite each other, as they will thus exert a gripping effectagainst each other.

The block is provided around its sides with the desired number ofrecesses 10 which is covered by a slotted plate 11 having front and rearvertical members 12 and 12 with a blade 13 to enter the rear wall of therecess, and with the assistance of the screws 14 at the front end,retain the plate in its place. The front vertical member 12 is set intothe block so that it is flush with the edge of the block.

Along each side of the block is then secured a metallic strip 15 and onthe outer face of the latter is secured the second metallic strip 16which is recessed for the operation of the levers.

Journaled in the plate member 12 and the plate 15 is a shaft 18 one side19 of which Specification of Letters Patent.

is cut away and the shaft carries at its outer end an arm 20' to rotatesamewhile it plays in its recess between the two strips-15*and 16, andon'the upper face of the plate 11 plays a jaw 21 with a stem 22 toenterthe slot in the plate 11 and 'descendinto the recess 10. The stem'22 has a slot 23 for the passage of the shaft and about this stem andbeneath the lower side of the plate 11 is a rectangular collar 24resting'on the shaft 18 leaving a distance betweenits lower side and thebottom of the slot 23a little less than the diameter of the shaft. Thegripping face of the jaw is inclined to fit the beveled edge of thestereotype plate 25: and its under side is serrated to more securelygrip the plate 11.

lVlien a stereotype plate is placed on the block the jaws 21, beingloose as in Fi-g. 5, are brought against the edge of-theplate and thearm 20 is carriedfrom the vertical position as in Fig. 5 to thehorizontal as shown in Fig. 1 causing the flat edge 19to assumea'vertical position and the diameter of the shaft to fill the spacebetween the lower side of the slot and the collar which I around theblock and the movement of the cylinder of the press always insures thelooking action of the jaw.

What I claim as new and desire to secure by Letters Patent is:

1. A stereotype block provided with a recess, a slotted plate secured tothe block opposite said recess, a jaw arranged to operate in the slot ofthe plate and provided with a pendent stem in'which'an opening isformed, a shaft journaled in opposite walls of the recess and passedthrough the opening in the stem of the jaw and provided with a camportion extending sub stantially the entire length thereof, means forturning said shaft, and cooperative means between the shaft, jaw, andplate to cause a binding of the jaw upon the slotted plate to hold thejaw in the adjusted position.

2. A stereotype block provided with a recess, a slotted plate secured tothe block opposite the recess, a jaw slidably mounted in said slottedplate and having a pendent stem formed with an opening, a shaftjournaled at its ends in opposite walls of the recess and passingthrough the opening of the stem of the jaw and having a cam portionextending substantially the entire length thereof, cooperative meansbetween the shaft, jaw, and plate to cause a binding of the jaw uponsaid plate, a lever fitted to the outer end of the shaft, and a stripsecured to the block and spaced therefrom to receive said lever afterthe same has been operated to effect securance of the jaw in theadjusted position.

3. In combination a stereotype block provided with a recess, a slottedplate arranged opposite the recess and provided with pendent membersentering said recess and forming walls thereof, a jaw mounted in theslotted plate and having notches in opposite sides to receive the edgeportions of the plate bordering upon the slot, and having a pendent stemformed with an opening, a shaft journaled in the pendent portions of theslotted plate and passing through the opening of the stem of the jaw andformed with a cam portion extending approximately the entire lengththereof,

means for turning said shaft, and cooperative means between the shaft,jaw, and plate to hold the jaw in the adjusted position.

4. In a stereotype block, the combination with a block having lateralrecesses, of slotted plates covering the recesses, jaws adjustable alongthe upper sides of the plates and serrated on their under sides, slottedstems depending from the jaws, loose collars on the stems and impingingthe lower sides of the plate, shafts having a flattened side and playingin the slots of the stems to cause the jaws and the collars to grip theopposite sides of the plates and levers at the ends of the shafts toturn same.

5. In combination a stereotype block having a recess, a slotted platesecured to the block over the recess thereof and having pendent membersentering the recess, the inner member having a projecting portionextending into the inner wall of the recess near the bottom thereof, aaw mounted in the slotted plate and having notches in opposite sides toreceive the inner edge portions of the slotted plate bordering upon theslot thereof and having a pendent stem formed with an opening, a camshaft journaled in the pendent portions of the slotted plate and passingthrough the opening in the stem of the aw, a collar mounted upon thestem of the jaw between the slotted plate and cam shaft, spaced stripssecured to an edge of the block, the inner plate havin the outer end ofsaid cam shaft journaled therein, and a lever fitted to the projectingend of the cam shaft and adapted to lie in the space formed between saidspaced plates.

In testimony whereof I afliX my signature in presence of two witnesses.
